Master filer Matthew Cornell says when you grab a folder from your filing cabinet, you should "bookmark" where it should be returned:

When you pull a file, simply lift up the file behind it a few inches and let the remaining files in front of that one lean back. You'll find they keep the bookmark file up above the rest until you're ready to return the pulled file.

Anything to avoid ruffling through file folders more than usual! Matthew's got a few other "master filer" tips, including making the manila folder crease work for you, flattening thick folders and using a magnetic bookend as a backstop.
